According to the USDA, National Agricultural Statistics Service (NASS) June 10 Crop Progress report, as of June 9, 95 percent of the corn crop had been planted, compared with 100 percent at the same point last season and 98 percent for the 2008-12 average.

Iowa, Minnesota, North Dakota, and Wisconsin were well behind the normal pace. Corn emergence statisticsreveal more of the effects of cool, wet weather on this year’s corn crop, with only 85 percent emerged as of June 9 compared with 99 percent last season and 92 percent for the 2008-12 average.

As would be expected, emergence was well behind normal in the same States where planting wassignificantly delayed. Corn rated good or better comprised only 63 percent of the 18-State total, compared with 66 percent at the same point last season.

Early-season crop condition ratings often provide little indication of final yields as rainfall and temperature over the next several weeks will ultimately determine this year’s production. The percentage of the crop rated good or excellent was 69 percent in 2011, 66 percent in 2012 for reporting weeks comparable to June 9 of this year. The U.S. corn yield in 2011 was 147.2 bushels per acre. The 2012 yield was 123.4 bushels per acre, 33.5 bushels below the 1990-2012 simple linear trend.
